Lesson details
Key learning points
- A positive exponent tells you how many identical values must be multiplied together.
- Dividing by 10^n is the same as multiplying by its reciprocal.
- A negative exponent tells you how many reciprocals of the base must be multiplied together.
- a^(−3) = 1/a^3
Keywords
Exponential form - When a number is multiplied by itself multiple times, it can be written more simply in exponential form.

A negative exponent implies that the entire value is negative.
Refer back to the table showing the structure of how the negative exponents occur and highlight that none of the decimal values are negative.
